PIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 691 ,346, dated January 21, 1902.

Application filed October 9, 1900. Serial No. 32,606. (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER BARR, engineer, of 6 Hillend Gardens, Partickhill, in the county of Renfrew, Scotland, have invented certain new and useful Improvements in Pipe-Couplings, of which the following is a specification.

This invention has mainly for its object by an inexpensive and efficient means the connecting or joining of metallic pipes to ar: ticles or receptacles made of glass, potteryware, or other more or less fragile material of a like nature.

Figure 1 is a vertical section through my coupling and two pipes. Fig. 2 is a top plan View of the same.

In carrying out my invention as applied to such articles as water-closet basins, wash hand-basins, and the like, reference being made to the accompanying drawings, I form the short pipe or nozzle A, which is a part of the receptacle for the supply or discharge of the same, of an increased outside diameter at the point of connection with the metallic pipe B. I also employ a metal collar or gland O,'the inside diameter of which permits of the aforesaid nozzle A being freely'passed through it. After having passed the nozzle A through the collar or gland O, I pass the nozzle A into a short piece of india-rubber pipe or ring D or other suitable material, which having thus increased the outside diameter of the nozzle prevents a complete return of the gland. The metallic pipe B to be connected being formed of a more or less like configuration to the said nozzle A and also provided with a similar gland O and rubber piece the joint or connection can then be securely formed by drawing the two glands together by means of two or more bolts or nuts EE'. A rubber or other packing ring may be used between the connecting-surfaces, or in lieu thereof a portion of the rubber pipe or ring may be turned inward at point of contact. When the pipe to be connected is of lead or other more or less soft material, the

inside'diameter of its gland may be of a di-.

ameter approximating the outside diameter 'of the pipe and the latter flanged outward,

"from completely returning byincrcasing the outside diameter of the ends of the pipe or pipes by means of a pipe or ring of rubber or other soft material being put thereon.

I claim In a pipe-coupling the combination with pipe having an increased outside diameter at one end, the gland having a decreasing interiorthe smallest diameter of which is greater than the greatest outside diameter of the pipe'whereby the gland may he slipped over the end of said pipe, a rubber packing secured around and over the end of the pipe thereby preventing the gland from passing over the end of the pipe, in combination with another pipe having a flange on its end, a gland secured around the second-named pipe and clamping-bolts connecting the two glands.

In testimony whereof I affix my signature in the presence of two witnesses.

ALEXANDER BARR. I
